Transcript of Brain dissection pictures
This opaque covering is the dura
The meninges cover and protect the brainFrom outer to inner they include:1. Dura
-tough outer layer we took off2. Arachnoid
-The Cerebral Spinal Fluid (CSF) flows between the Arachnoid and Pia layers and serves to nourishand protect the brain & spinal cord.
3. Pia-pearly layer extends intothe sulci

The shiny coating is the Pia Mater
The Pia Mater is the innermost meningeal layer.It extends into the sulci.

SPINAL CORD ANATOMYKeep in mind that our models are HUGE. The spinal cord
Is really only about the thickness of your pinky finger!
This is the URL to a sheep dissection lab created by five students in the bi-college (Haverford and Bryn Mawr) community: Jessica Kuhn, Jessica Magid, Karen Revere, Elizabeth Caris, and Gray Vargas through science education at Bryn Mawr College. It is a fantastic site to explore the brain. Not everything you will learn will be on a test BUT remember that educating yourself in your field is NOT about what is going to be on the test .
TRY THIS TO TEST YOURSELF!!
